This is currently an opt-in build flag. Once ASLR support is ready and stable it should changed to opt-out and be enabled by default along with ASLR. Each application Makefile uses opt-out to ensure that ASLR will be enabled by default in new directories when the system is compiled with PIE/ASLR. [2] Mark known build failures as NO_PIE for now. The only known runtime failure was rtld. [1] http://www.bsdcan.org/2014/schedule/events/452.en.html Submitted by: Shawn Webb <lattera@gmail.com> Discussed between: des@ and Shawn Webb [2]

# Option file for src builds.

#
|
|
# Users define WITH_FOO and WITHOUT_FOO on the command line or in /etc/src.conf
|
|
# and /etc/make.conf files. These translate in the build system to MK_FOO={yes,no}
|
|
# with sensible (usually) defaults.
|
|
#
|
|
# Makefiles must include bsd.opts.mk after defining specific MK_FOO options that
|
|
# are applicable for that Makefile (typically there are none, but sometimes there
|
|
# are exceptions). Recursive makes usually add MK_FOO=no for options that they wish
|
|
# to omit from that make.
|
|
#
|
|
# Makefiles must include bsd.srcpot.mk before they test the value of any MK_FOO
|
|
# variable.
|
|
#
|
|
# Makefiles may also assume that this file is included by bsd.own.mk should it
|
|
# need variables defined there prior to the end of the Makefile where
|
|
# bsd.{subdir,lib.bin}.mk is traditionally included.
|
|
#
|
|
# The old-style YES_FOO and NO_FOO are being phased out. No new instances of them
|
|
# should be added. Old instances should be removed since they were just to
|
|
# bridge the gap between FreeBSD 4 and FreeBSD 5.
|
|
#
|
|
# Makefiles should never test WITH_FOO or WITHOUT_FOO directly (although an
|
|
# exception is made for _WITHOUT_SRCONF which turns off this mechanism
|
|
# completely).
